PDF seems to be working now.
As for NP3. The stuff is great, but only when appropriate. The M&P simply isn't tight enough frame to rails to bother for that. About the only internal piece I think MIGHT benefit would be the sear block, but that's a big maybe.
The only thing on the M&P I'd seriously consider getting NP3ed would be the magazines. NP3ed magazines are very nice if you can afford them. Very slick without being slippery and clean up in a snap.
I have a question for dan or anyone else who has done a trigger job on the M&P. I got myself a trigger scale, and assuming it can be relied upon, I was rather shocked at the trigger pulls on a lot of my guns. I was only right about one of them.
Apparantly I'm pretty happy with a smooth pivoting trigger of about 4lbs, or a crisp short trigger like a 1911 up to about 5lbs.
So question 1 is, how smooth is a 4lb trigger job on an M&P?
Question 2 is does the trigger job described in the pdf, which I assume is the same one you do more or less, increase the ammount of pre-travel/takeup? I've got pretty long fingers and pretty large hands, and I'm not real fond of triggers that break WAY to the rear (ala berettas and such).
